reduce inefficiency of anti-muon discriminator in high pile-up events:
	- do not veto track segments in innermost CSC chamber
	- count number of muon stations containing matched segments
	  rather than summing matched segments of different muons in the same muon station
	 (in the old implementation a tau was failing the anti-muon Loose discriminator in case there are 2 reco::Muons
	  each having 1 matched segment in the innermost CSC chamber. The new implementation requires that the matched segments are in at least 2 different chambers
	  before the tau fails the anti-muon discriminator)
